I havent posted in a while, but here goes..
I brewed a (dang good) stout based off Tuck's recipe. I made a dumb mistake and didnt prime the first 12 or so bottles. So I primed the majority the right way, finished my bottles, then dumped the 12 bottles back into the bucket, primed it, then filled my bottles again. I've used that method maybe twice before.. I always forget to prime.
Anyway, I was smart enough to separate the ones I did right and my screw ups. I tried a screwup about 3 weeks ago and it smelled like peaches but tasted fine... Any guesses on that one? I've been working a lot lately but I dont recall reading about peach scent being related to any contamination (but I could be wrong).
I have read that, in other food applications, peach smells is a sign of some toxin. I drank the "peach stout" before I read that, and it didnt seem to hurt me or the 3 other people that tried it.
The other bottles by the way... Outstanding brew. Inch thick brown head, the initial bitterness mellowed out very well, sweet, but not too sweet, I could go on...
Any guesses on the problem?
